Filed: 1998-07-16
Abstract: PROBLEM TO BE SOLVED: To attain the reduction of cost by omitting a magnet which accounts for a major component in cost in a disk holding mechanism, without necessitating the magnet for attraction at a center hub of a turntable. SOLUTION: As to the disk holding mechanism for pressing and holding the disk 10 on the turntable 14 by a clamper 16, the disk holding mechanism is formed to clamp the disk in such a manner that the outer periphery 16a of the clamper is held in a suspended state by plural leaf springs 19 at the time when the disk is not mounted and the clamper is pressed and held by the elasticity of the left springs at the time of chucking the disk, and the leaf spring is provided with a holding part for holding the disk, and the holding part is furnished with a fork part 18 composed of an upper fork 18a and a lower fork 18b to form a gap 18d. Then, the supporting structure without using the magnet is obtained by loosely fitting the outer peripheral part 16a of the clamper to the gap part 18d between the upper/lower forks 18a and 18b.
